Inventor: OKUSA MIDORI
IPC: G06T7/60
Filed: 1991-12-10
Abstract: PURPOSE:To directly perform the arithmetic processing of area/SIGMA calculation on the basis of only an outer periphery by performing branch processing by the combination of the chain code going in and out concerning to a pertinent picture element on the outer periphery. CONSTITUTION:The data of eight picture elements neighboring to the starting point of tracing is investigated counterclockwise (ST2), and a tracing direction value is determined and made to be the chain code (ST3). A case is classified into four kinds of the case that the pertinent picture element is the right end of a figure pattern to be traced, the case that it is the left end, the case that it is protruded by one picture element beyond the figure pattern, and the case other than these (ST5) in accordance with the combination of the chain code before and after the movement of the pertinent picture element (ST4). Prescribed addition or subtraction operation is executed at every classification (ST6). In the case that nothing is done, if one round of the tracing of the outer periphery of an objective picture for which nothing is done is finished (ST7), it is drawn out of the loop of the generation of the chain code. A center of gravity and a principal axis of inertia are calculated by using an area/SIGMA values obtained by the above-mentioned processing (ST9).

Abstract: PROBLEM TO BE SOLVED: To prevent the residual of sulfur component in a phosphor film in a slurry method of forming phosphor film. SOLUTION: A washed glass board is formed with the predetermined pattern of an ITO film, and a pre-coating film is formed thereon. The pre-coating film is coated with the slurry liquid for blue color phosphor film containing the blue color emitting phosphor (Y2 SiO5 Ce), photosensitive material, dispersant, pure water and WO3 , and it is dried so as to form a coating film at 1.2 mg/cm<2> . The WO3 content is set at 0, 0.3, 1, 3, 5, 10 wt.% in relation to the phosphor. The coating film is exposed, and developed with water. A phosphor film having a desirable pattern is thereby obtained. A result of quantitative analysis of the sulfur content of the phosphor film is showed.  Effect of reduction of the residual of sulfur is confirmed in a range at 0.3-10 wt.% of WO3 , and especially a remarkable effect is recognized at 1 wt.% or more, and the effect becomes nearly zero at 3.0 wt.% or more. The optimal value of the WO3 added variable is 1-3 wt.-%. In the case where this phosphor film is used for display element, amount of sulfur scattered at the time of irradiating electron beams to the phosphor film is reduced, and lowering of the emission of a negative electrode due to the contamination by sulfur is prevented.
